Preferably, the thicknesses of the first cement board, the second cement board and the third cement board are all set to be the same.
Preferably, the filling layer is in particular an acoustic felt layer.
Preferably, the keel is in an I-shaped arrangement, and the keel is provided with a fillet.
The utility model provides a pair of prefabricated outer wall structure that possesses syllable-dividing effect, beneficial effect lies in: this prefabricated outer wall structure that possesses syllable-dividing effect can utilize three cement board collocation fossil fragments to construct the basic frame of outer wall, and in the time of the save material spending, stability does not change, sets up multiple sound-proof material simultaneously between the cement board for the holistic syllable-dividing effect of outer wall strengthens.
Drawings
Fig. 1 is the utility model provides a prefabricated outer wall structure's that possesses syllable-dividing effect schematic structure diagram.
Fig. 2 is the utility model provides a possess the sound insulation effect's of prefabricated outer wall structure's puigging's structure enlargements.
In the figure: the sound insulation board comprises a first cement board 1, a second cement board 2, a sound insulation layer 3, a net rack 31, a paper surface gypsum board layer 32, a sound absorption cotton layer 33, a keel 4, a third cement board 5 and a filling layer 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
Referring to fig. 1-2, a prefabricated outer wall structure that possesses syllable-dividing effect, including first cement board 1, second cement board 2 and third cement board 5, and second cement board 2 is located between first cement board 1 and the third cement board 5, be provided with filling layer 6 between two adjacent fossil fragments 4, and filling layer 6 is located between second cement board 2 and the third cement board 5, filling layer 6 specifically is the sound-proof felt layer, the sound-proof felt has fine syllable-dividing effect, pack the sound-proof felt between second cement board 2 and third cement board 5, thereby soundproof effect has been improved.
The sound insulation layer 3 is compositely bonded between the second cement board 2 and the first cement board 1, the sound insulation layer 3 specifically comprises a net rack 31 bonded on one side of the second cement board 2 opposite to the first cement board 1, the inside of the net rack 31 is hollow, paper gypsum boards 32 are compositely bonded on two sides of the inside of the net rack 31, a sound absorption cotton layer 33 is compositely bonded between the two paper gypsum boards 32, the thickness ratio among the net rack 31, the paper gypsum boards 32 and the sound absorption cotton layer 33 is 1:2:8, and the net rack 31, the paper gypsum boards 32 and the sound absorption cotton layer 33 are bonded according to the thickness ratio of 1:2:8, so that the net rack 31 has a good protection effect on the paper gypsum boards 32 and the sound absorption cotton layer 33, the adsorption of external noise is improved, and the sound insulation effect of the external wall is effectively improved.
Example 2
